I spent a few years diving San Clemente Island and Cortez Banks for abalone and black coral. As soon as we had 100 dz. abalone, we would radio San Diego and our abalone buyer would come out with their boat and buy our abalone on the spot with cash and bring us fuel, water, food and what ever else we needed to stay out at the island and dive. So every 3 days they would come out. There were some old navy udt frogmen Korean war vets that where also out diving for abalone. So we became good friends because they only dove deep and sometimes it took longer to get 100 dz. abalone for them. So by us getting 100 dz. every few days, they could use our pick-up boat for selling their abalone and get supplies too. They showed us where there was Black Coral growing off the south end of San Clemente Island at about 175" deep. The tops of the rock pinnacles were at about 90' and went down to 210'. With giant Black Coral bushes growing out the sides. Bigger than anyone even knew existed. We never dove deep so they showed us how to do it. We bought analong decompression meters and went for it. At that depth, we only had about 12 or 15 minutes bottom time. So we could only get 2or 3 bushes for that one dive for the day. So we did it on our last diving day at the island. We could sell one bush, as a specimen for big bucks to asians. We did good for awhile. Then I got married and figured I needed a different job. The Government found out that there was Black Coral out there in 2005 and how unique and big they are, then they outlawed harvesting them and made them a protected species. No one even knew they existed. There are a few things out there in those waters and Cortez Banks that no ones knows exist. Giant species of known life forms that no-one knows get that big and I"m glad they don't know. The Channel Islands are a very unique place where no-one dives deep to see what is there. We dove with hookah rigs and air hoses, and compressor.
